The Renesas MicroClock family of ultra-low-power, miniature programmable clock generators help maximize battery life and decrease solution size of wearables, hearables, smart devices and embedded systems. Each device includes three outputs, selectable frequency options from 1 to 100 MHz and configurable spread spectrum clocking to reduce EMI. 

The MicroClock programmable clock generators are all equipped with innovative features and low-power DCO to support battery-powered device requirements. Each device is OTP programmable to allow for up to three unique frequency outputs

Features and Benefits

  • Ultra-low power consumption 
  • Small packages reduce board space and lower BOM costs
  • Proactive Power Saving (PPS) actively switches modes according to downstream clocked component status
  • Dedicated OE pin for each output minimizes power consumption based on performance requirements 
  • Dynamic Frequency Control (DFC) allows fast changes between pre-selected frequencies 
  • Spread Spectrum technology attenuates system EMI 
  • Multiple output swing options for SOC with low swing clock requirement 

Comprehensive Development Tools

  • Simplify design process and speed time to market.
  • Dev kit with USB programming board, Timing Commander™ GUI and blank socket devices enable rapid programming
  • Tiny evaluation board allows easy verification on an existing system board
